GMK probably wouldn't be too hard with such a small set to reach MOQ and the price wouldn't be too high. Only there is still 2 caveats. One, they will NOT do the Cherry logo, I already asked them and they told me no because it's a trademark they don't own or have license to. Two, they aren't cutting custom legends yet so no geekhack key unless want to go with pad printing.
GMK isn't impossible to deal with, they are just used to corporate and industrial customers that probably order 1000+ at a time. They just aren't used to dealing with us yet. Hopefully in time they will re-evaluate their MOQ policy to be more accommodating.
I was planning on offering something small along the lines of this as it was since the full set isn't going to happen anytime soon at least. Perhaps this can be one of those things, but perhaps different colors? Maybe dark grey on orange like inverted Skidata?
